RIDGE CUTTER.

Application filed November 5, 1927. Serial No. 231,284.

The present invention relates to a ridge cutter and has for its prime obj ect to provide an exceedingly simple frame construction which may be coupled to a tractor for moving along the ground a plurality of pairs of discs disposed at an angle for throwing the dirt outwardly.

rrnother important object of the invention resides in the provision of a frame structure in a ridge cutter of this nature wherein the parts may be assembled in a strong and rigid manner to attain a high degree of etticiency.

with the above and numerous other objects I in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is a side elevation of a ridge cutter embodying the features of my invent-ion,

Figure 2 is a top plan View thereof,

l igure 3 is a rear elevation thereof,

Figure 4 is an enlarged detail vertical section through the adjustable mechanism for mounting the discs on the frame, and

Figure 5 is a detail section through the frame taken substantially on the line 55 of Figure 2.

Referring to the drawing in detail it will be seen that numerals 5 denote a plurality of discs arranged in pairs. Each pair of discs are rotatably mounted on the extremity of yoke (3 depending from a shank 7 rocliably mounted in a bearing block 8. Th is clamp block b is rocliablc on a pintlc 9 formed by e2:- tensiims from an sections it) and ll which are bolted together as at A nut segment it extends rearu'ardly from the section ll. A. crank extends from the upper end of the shank 7 and has a spring pressed catch 16 engagcable with the notches of the segment An arm 1? rises from the bearing block 8 and has a bolt 18 extended therefrom with a nut 19 thereon. The arm 18 has a lateral extension through which the bolt 18 extends, this lateral extension being adapted for engagement with notches of a segment :21 rising from the section 10. The parts thus far described are conventional in the cultivator art and have been illustrated merely to bring out clearly the utility and advantages of the fran'ie structure about to be described.

Referring to the frame structure in detail it will be seen that numerals 25 denote a pair of frame bars the forward ends of which are fixed together and from which the bars extend rearwardly and diverge from each other so that the rear ends terminate in spaced relation. Hooked bolts 26 are mounted in the rear extremities of the bars 27 with the hook ends disposed downwardly and supporting a cross bar 27 of suliicient length to extend between and beyond the rear ends of the frame bars 2'. Rods 28 and 29 are fixed to the for ward portions of the bars 25 one 011 top of one bar 25 and the other under the other bar These rods 28 converge from their rear ends forwardly so that their forward ends are disposed one above the other and are apertured as at 29, said apertures being in vertical registry to receive a pin 30 for engagement with the draw bar, clevis or like of a tractor.

cross bar 31 is disposed across the intermediate portions of the frame bars 25 being bolted to the upper surfaces thereof as at 32.

1 Connecting rods 33 are pivotally engaged as at Set with extensions 35 on the lower Jaw sections 11 and extend forwardly to rest on top of the cross bar 31 being clamped thereon by means of a clamp rod 36 which is bolted to the frame bar 25 as at 37. Thus the cultivating parts of conventional construction are securely and rigidly mounted on the frame structure. The frame structure is very simple and because of the arrangement of its parts with respect to one another is very strong and durable. Furthermore this frame structure affords a mount for the cultivating parts allowing exceedingly desirable ease of assembly and disassembly.-

It isthought that the construction, operation, utility and ad *antagcs of this invention will now be cl early understood by thoseskilled in this art without a more detailed description thereof. The present embodiment of the illvention has been disclosed in detail merely by way of example since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description. It will be apparent that changes in the details of c011- struction, and in the combination and arrangement of parts may he resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is: i

In a ridge cutter of the class described, a

upper surface of one bar and the other to the under surface of the other her, said rods converging forwardly to terminate one above 1 the other, the forward ends being apertured in a-linenlent.

In. testimony whereof I afiix my signature.

DAVID W. WALKER.
